[jira] [Updated] (IGNITE-9531) ZookeeperDiscovery
testClientReconnect is flaky in master
[ https://issues.apache.org/jira/browse/IGNITE-9531?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]
Alexey Platonov updated IGNITE-9531:
------------------------------------
Description:
The test IgniteClientReconnectCacheTest#testReconnect periodically.
From the logs I see that the hang is caused by assertion error:
{code}
junit.framework.AssertionFailedError: expected:<22> but was:<null>
at junit.framework.Assert.fail(Assert.java:57)
at junit.framework.Assert.failNotEquals(Assert.java:329)

was:
The test IgniteClientReconnectCacheTest#testReconnectMultinode(LongHistory) periodically fails with timeouts in master.
From the logs I see that the hang is caused by one of the two assertion errors:
{code}
java.lang.AssertionError

or
{code}
java.lang.AssertionError
at org.apache.ignite.spi.discovery.zk.internal.ZookeeperDiscoveryImpl.checkClientsStatus(ZookeeperDiscoveryImpl.java:1388)

at org.apache.zookeeper.ClientCnxn$EventThread.run(ClientCnxn.java:498)

The test failure can be rarely reproduced locally (run repeatedly with CPU stress enabled).
